Load Balancing to 2 Instances in a 4-Tier System

Problem:
          I need to load balance requests from a cluster of JRun JSP servers through
          an IP(IP2) to a set of servers on tier3 containing 2 instances per box, that
          are not clustered. I have used WLBS to proxy through IP2 to each machine in
          tier 3. Heres the kicker -- I can't figure out how to proxy to 2 instances
          on each of the dual processor Win2k boxes. Does anyone know? I have 2 IPs on
          each box but WLBS won't proxy to 2 IPs on the same box. I am looking for a
          software solution.
          Thanks,
          Mica Cooper

CF 10 Load-Balancing with Remote Instances

I was reading an article on Clustering/LB/HA using CF8, but have not found any updates for CF10.
Using VM VirtualBox to setup a few virtual servers, I am looking to setup a load balancing of ColdFusion 10 on 2 remote instances. The goal would be have ColdFusion Cluster Manager be able to point http request to one of the two servers based on load/availability. Not really having a hardware cluster/failover setup, just managing resources on two CF instances instead of a standalone.
The servers are Windows Server 2008 R2 with IIS7.5 and ColdFusion 10 Enterprise on installed on 3 of these machines. Let's call them CF-LBManager, CF-Web1, and CF-Web 2. In the CF Docs, they show the Cluster Manager adding the local CF instance and "if you want" a remote instance. However, this scenario would require the main instance to be running and not fail for it to direct to the other instance.
I am trying to set this up now with CF-LBManager as just a manager of the requests coming in. In the Enterprise Manager >> Instance Manager, the local instance is shown and I add the two remote instances with the correct Remote Port, JVM Route, etc. I also made sure the <Cluster>...</Cluster> block was added to the two remote instances (CF-Web1 and CF-Web2) \runtime\conf\server.xml file too, Jetty Services also is running. Now under the Enterprise Manager >> Cluster Manager I add the two remote instances to the cluster, not the local instance on CF-LBManager with Multicast Port and Sticky Sessions enabled. On Submit, I get a green message "You must restart all the server instances and any configured webservers for these changes to take effect.". I go ahead and reboot the servers and come back.
I now browse to the ColdFusion page as a test on CF-Web1 and CF-Web2 to make sure CF is running properly, they do. I then browse the IP of the CF-LBManager, however it only returns the local IIS web site and not redirect to one of the two cluster members. I am not seeing any message on the coldfusion-out.log on the remote instances. Am I not setting this up correctly or not enabling the Cluster Manager to take over and pass along the requests to those in the cluster?

Unfortunatley I don't have a lot of experience with CF10 on Windows, but if you are running CF behind IIS I think you will need to update the Tomcat connector configuraiton to do load balancing. I'm not sure if re-running the wsconfig tool on all of the servers will do this or not, but that is what I would suggest trying first. If that doesn't work you will need to update the Tomcat connector configuraiton manually. You can find more information on load balancing with the Tomcat connector here: http://tomcat.apache.org/connectors-doc/generic_howto/loadbalancers.html.

Load balancing BSSV multiple instances - what is your experience?

Hi,
we encountered an issue: we have three weblogic instances running BSSV Server instances for our JDE. THE BSSV instances are being communicated by SOA mostly and we would like to load balance the traffic between those three bssv servers. The problem is we need to use a certificate in order to load balance https.
The question is: has anyone of you performed such or similar operation before? What approach would you advise/recommend based on your experience? We will not use weblogic/webcache load balancing.
Thanks.

I haven't found a specific JDE forum to have this question addressed by JDE. So, I will try to help from Weblogic Server perspective.
Is JDE installed in a SOA weblogic server environment?
If so you can follow SOA EDG which covers load balancing.

Health check for load balancing ALSB/OSB instances

What is the standard practice for a load balancer sitting in front of ALSB/OSB instances as far as a health check? I'm working with our IS department to implement a valid health check. Currently the load balancer (older model cisco device) is just checking for an active port which is generating excessive logging on the ALSB side. As a workaround I'm just going to have the loadbalancer check for a http 200 response and a greater than zero body size.
thanks in advance...

it depends on the type of load balancer what it can do. I suggest create a 'empty' proxy service that does not have logging or auditing. Publish the prox and use this webservice in your load balancer to check if the service is available.

Load balancing between Instance for same external IP client

Hi,
I have a azure website which is single tenant and is going to be used inside a single Domain from same region.
Now my website provide good performance till 20 concurrent request. I want to scale this so that it can reach up to 30 - 40 -100 so on.
What are the options available to achieve this. till now what i have figured out is that
1. If i increase the web site instance or on the auto scale option. It load balances between the instances on the basis of Client external I.P. but in my case all the users which are using the site shares the same external IP.
I have tested it increasing the instances doesn't make any impact on my performance results.
2. I have also looked in traffic manager but that case is valid when the clients are on different GeoLocations which is also not valid in my case.
So my basic Question is if i have a pool of different scenarios where
100 users uses 1 azure website
200 uses uses 1 azure website
1000 users uses 1 azure website
what infra should i take for each website to support this have performnace same as 100 users.

Hi,
I would request you to configure Web hosting plan and check if it helps in increasing the performance.
It gives a set of features and capacity that you can share across your websites separately.

WebAS access via Portal: Web Dispatcher required for load balancing ABAP

Hi Folks -
We have EP 6.0 SP18 (Java only, WebAS 6.40, Unix/Solaris). The portal has a CI/SCS and one DI so we have a Web Dispatcher to load balance the portal servers. This works fine (and provides port 80 access).
This portal will provide access to HTTP services from an ABAP WebAS (6.20 with 6.40 kernel, Unix/Solaris). A landscape configuration entry has been added to the portal for this ABAP system. The ABAP system has a CI and multiple app servers, all capable of handling HTTP requests. This will also require port 80 access.
1. Will we need an additional Web Dispatcher to load balance HTTP requests to the 'backend' ABAP WebAS system, or will the portal be smart enough to handle the load balancing itself (perhaps based on the information in the landscape configuration)?
2. If the portal itself handles the HTTP load balancing can you point me to documentation (so I can make sure I have proper configuration)?
3. Are there any changes to this with NW2004s Portal (we plan to upgrade soon)?
Thanks in advance! Jeff

Jeff,
Regarding:
Q1. If you create a system object from the "SAP system with load balancing" template in portal and configure the object to point to your CI (msg server), the LB should be handled.
Q2. Portal load balancing is handled by the message server. If you point a test URL to the port of your message server, you will notice that you are issued a redirect the URL of your dialog instance. The web dispatcher is just a proxy (with some intelligence). When a request is made to the WD, it makes a connection to the MSG server, the list of active instances is queried, a redirect is made to that instanct. If you use WD, that connection can be proxied behind a standard URL. If you connect directly to the MSG Server instead, you will notice your URL change, just as it does on the service marketplace.
WDs are good for providing services, masked (proxied) behind virtual names. If you do not want the customer to see a physical URL of the server, use the WD. There are lots of other solutions that can do this too though such as Apache, ISA, Juniper devices, Cisco LDs. WDs have a very low performance threshold though, especially if you use SSL. WD is a performance bottleneck and should be benchmarked to see if it is right for your application.
Q3. No changes this architecture in 04s.

Load Balancing & Fault tolerance in Oracle Apps

Hello
I am pretty new to Oracle Apps and Oracle 9iAS
We are trying to asked to find out the ways of deplying load balancing and fault tolerance in Oracle Apps
I have gone thru the following articles of metalink and some more from google
Configuring Web Cache as a Load Balancer for Application Servers
Create new middle tier node in existing Apps 11i environment using cloning and then load balance
Integrating and using Web Cache with Forms 9i for Load Balancing
Running Multiple OC4J Instances From a Single Install of 9iAS 1.0.2.2
LOAD BALANCING ORACLE APPLICATIONS ON UNIX
Load Balancing in 11i
OC4J Clustering Setup
OC4J Load Balancing for Forms 9i
Setting up 11i E-Business suite using a hardware load balancer
Sharing an APPL_TOP in Oracle Applications 11i
In Oracle Apps Concepts pdf, found that
Load balancing occurs when there are multiple installations of web server, forms server, reports server, concurrent manager server etc
Lets consider forms server component of middle tier
Can there be multiple INSTANCES of forms server within SINGLE INSTALLATION ???
If it has to be MULTIPLE INSTALLATIONS, then it will require multiple physical machines
What is software load balancing then ???
Also read that
Oracle 9i AS instance is combition of Oracle HTTP Server (OHS) and one or more instances of Oracle9iAS Container for J2EE (OC4J)
Thus software load balancing can be implemented for Web server component of middle tier using multiple instances of OC4J ???
Forms metrix server configuration is hardware load balancing ??
What about Oracle9iAS Web Cache clustering ??
Please clarify the doubts and suggest me the way
Thanks a lot

dear all can any one help me on the following;
We want to install Oracle Apps 11.5.9 on 4 IBM AIX 5L boxes, the first node
will hold the database , concurrent and Admin Tiers. as for the other 3 nodes
it will hold the Forms/Web Tiers and we need to use forms metrics for load
balancing taking into consideration that we can't use Shared APPL_TOP. we tried
to find the way how to install and configure this solution but all the
documents are talking aboout the concept only and this concept is applicable.
We need the exact steps on how do the installation either using rapidwiz or any
thing else

FRM-92101: Load Balancing Forms 10g with Web Cache

Hi,
IÂ´m having some problems with Oracle Forms and Webcache 10g and I was wondering if you
could help.
Machines: (Pentium IV 2.6 GHz; 2GB RAM; 80GB HD)
A. Red Hat Linux AS 2.1
Oracle AS 10g - Infrastructure Installation
B. Windows 2000 Server - Service Pack 4
Oracle AS 10g - BI and Forms Installation (Using Infrastructure on machine A)
C. Windows 2000 Server - Service Pack 4
Oracle AS 10g - BI and Forms Installation (Using Infrastructure on machine A)
I didnÂ´t apply any Patchsets of Oracle AS 10g. My current version is 9.0.4.0 .
Goal:
Use Oracle Webcache 10g on machine B for Load Balancing an Oracle Forms Application
on machines B and C.
Facts:
The Oracle AS 10g installation on the 3 machines was made without problems.
The Forms Applications are running without problems on both Forms servers in machine B and C.
Symptoms:
IÂ´m getting the following error when I try to acces the forms application through Webcache:
FRM-92101: There was a failure in the forms server during startup.
This could happen due to invalid configuration.
Please look in the web-server log file for details.
But, this error happens ONLY when BOTH OC4J_BI_Forms instances (machines B and C) are
running.
When just one of the OC4J_BI_Forms is running everything works fine.
Webcache Configuration:
IÂ´ve followed Metalink note 207668.1: Configuring Web Cache as a Load Balancer for Application Servers
step by step to make the configuration of the following components:
1. Configuration of the origin servers
2. Configuration of Site definitions
3. Configuration of Site to server mapping
After that, IÂ´ve follwed the Metalink note 229900.1: Integrating and using Web Cache with Forms 9i for Load Balancing
step by step to make the configuration of the following components:
4. Session Binding
Then I try to test the Load Balancing and I got the error FRM-92101 when both OC4J_BI_Forms
instance were running.
IÂ´ve searched Metalink and found note 268830.1: Webcache Won't Load Balance 2 Forms Instances.
Following the note instructions I did the following changes:
Added these lines at the end of HTTPD.conf (machine B):
CookieTracking On
CookieName myformscookie1
Added these lines at the end of HTTPD.conf (machine C):
CookieTracking On
CookieName myformscookie2
In Webcache configuration:
IÂ´ve Changed the default session binding from JSESSIONID to "ANY SET COOKIE" for the
site's session binding.
But even after these changes IÂ´m getting FRM-92101 error on the same conditions.
How can I solve this problem ?
Thank you in advance.

Just ran into this problem last Tuesday, Nov.30 and applied the changes today.
My configuration is similar to yours: 9.0.4 web cache on machine A, 9.0.4 10gAS forms and reports standalone on machine B and C (not a cluster, no infra).
I appended the Cookie lines you mentioned in httpd.conf located in $ORACLE_HOME/Apache/Apache/conf in both machines B and C.
One important thing you may have missed. After changing httpd.conf in each 9iAS instance, you need to make the change known to dcmctl so issue:
dcmctl updateConfig -ct ohs
Then do the following for each 9iAS instance and it should be ready for webcache:
dcmctl stop
dcmctl start
Setup Any-set-Cookie in webcache instead of JSESSIONID and the whole thing should now work. You can run a form through machine A which will load balance to either machine B or C (which can both be up). Then, try shutting down 9iAS on machine B or C and run a form again. They now all work.
HTH,

Forcing traffic through load balancer rather than zone to zone

I have several T5140s with 2 LDOMs. Within each LDOM I have multiple zones which contain 2 environments. Each environment comprises the following, an apache instance behind a BigIP load balancer, a JBoss instance, and several misc. The jboss zone has three IP address assigned for multiple applications. Each server is configured identically as far as zone and LDOM layout. We use mod_cluster to cluster our apache and Jboss environment. What I'm trying to accomplish is forcing the apache zone's traffic through the BigIP rather than zone to zone.
Referring to the information below, server2ldom1jboss is one jboss node which needs to connect to both server2ldom1japache and server1ldom1apache. server2ldom1jboss connects to server2ldom1apache via its DNS name which is a NAT address. So webserver2 resolves to 10.10.2.5 which NATs to 10.10.1.5 behind the BigIP. webserver2 responds directly to the jboss zone rather than through the BigIP. Not good. server1ldom1apache works correctly as it's not a local zone.
Referring to this document, https://blogs.oracle.com/solarium/resource/solaris-container-guide-en-v3.1.pdf
section 5.2.7.8
"Connection of zones via external routers using the shared IP instance"
I've created the following routes
route add 10.10.2.5 10.10.1.5
route add 10.10.0.34 10.10.1.5 -interface -reject
route add 10.10.0.35 10.10.1.5 -interface -reject
route add 10.10.0.87 10.10.1.5 -interface -reject
route add 10.10.1.5 10.10.0.87 -interface -reject
route add 10.10.1.5 10.10.0.34 -interface -reject
route add 10.10.1.5 10.10.0.35 -interface -reject
This does prevent the zone to zone traffic, but it also preventing any response. I've tried other options as well, but have not been successful yet. What concerns me is this "These interfaces must not be used elsewhere in the global zone." The 5140 has 4 ethernet ports, which are configured into two port channels. vnet0 and vnet1. The apache instances use vnet1. The remaining zones use vnet0, including the global zone (server2ldom1 10.10.0.21). I think this may be the issue, but do not see an easy resolution without breaking my port channels and losing redundancy and fail-over.
If there is anything I'm missing or a better/different way to do this, I would greatly appreciate any input on this matter.
Thank you.

After further research, I think the best course of action will be to create a VLAN for the zone behind the BigIP and then create the corresponding interface in the vlan and zone. Using this links as my references in case anyone is interested. I'll post what I come up with.

Load balance based on OS

Is it possible to load balance incoming requests based on client's operating system on ACE?
For example, we have different web pages specifically for Blackberry or iPhones.
Instead of having multiple URL's & VIP's, we'd like to have a single VIP, but load balance traffic to different serverfarms based on client's OS.

You can loadbalance based on User-Agent header, first you need to quantify what Iphone and blackberry use for user-agent for instance from a regular browser you might see:
User-AgentT=Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 2.0.50727)
from an iphone you will typically see:
User-Agent=Mozilla/5.0 (iPhone; U; CPU like Mac OS X; en)
AppleWebKit/420+ (KHTML, like Gecko) Version/3.0 Mobile/1C25 Safari/419.3
you can go to http://www.user-agents.org to find out what strings are used
That being the case you can make classes on the header to match for loadbalancing decisions:
class-map type http loadbalance match-any mobile
2 match http header User-Agent header-value .*iphone
4 match http header Uswer-Agent header-value .*blackberry
then in LB policy say we want to go to farmA for mobile and farmB for pc's
policy-map type loadbalance first-match L7POLICY
   class mobile
     serverfarm farmA
    class class-default
    serverfarm farmB

Load Balancing for scheduled job in XMII V12

Hi XMII experts,
We are going to schedule a lots of jobs in XMII V12.
On our production server we have several JAVA Application servers.
Do you know if there is some kind of load balancing between java instance when we schedule jobs in XMII V12 ?
Regards
Jean-Louis

Hi,
If there is so many Applications in one Production server, then it will be overloaded. Suppose Java Applications and xMII Application are consuming lots of memory space and you are going to schedule lots of jobs in xMII, then it will be overloaded.
First you need to check how much memory your Java Applications and xMII Aplication is consuming. If it exceeds the RAM then system will be hanged.
Thanks,
Manisha

MULTIPLE LISTENER의 LOAD BALANCING 및 2개의 NETWORK CARD 사용 시 SETUP

MULTIPLE LISTENER의 LOAD BALANCING 및 2개의 NETWORK CARD 사용 시 SETUP
=====================================================================
Oracle V7.3의 SQL*Net 2.3의 새로운 기능으로 여러 개의 Listener를 띄우면서
상호 Load Balancing을 유지하는 기능을 소개하고자 한다.
Load Balancing 기능을 이용하여 각각의 Listener와 Oracle Instance 간의
Overloading을 줄일 수 있다.
다음의 예는 하나의 장비 내에 2개의 Network Card가 있을 경우에 대해 setup을
하는 방법이며 만일 하나의 Network Card가 있을 경우는 Host는 하나만 지정
하면 된다.
1. init<SID>.ora file을 지정할 Parameter
MTS_MULTIPLE_LISTENERS=TRUE

Oc4j load balancing AS 101202

Can anyone point me to some good documentation for configuring load balancing for oc4j instances?
I've seen a lot on metalink, but all dated back to 2002. I was hoping there was some new documentation for 10gR2.
I'm trying to load balance 3 webservice OC4J instances which each point to different API servers as the API servers themselves are single threaded.
Thanks for the assistance,
Tony

Thanks for the post. We had a little difficulty getting enough specifics out of the documentation to answer all our questions. But opened a TAR and got a good engineer who worked with us to get a custom load balancing solution that is working very well for us.
Thanks again,
Tony
For others out there that are interested, we ended up with a very simple load balancing setup that simply requires that the mod_oc4j.conf be modified to group the containers.
From Oracle:
To implement the solution, please execute the following steps:
1. Deploy application into different containers with the same application name.
2. Modify the mod_oc4j.conf as follows:
Oc4jMout /test <oc4j instance 1>, <oc4j instance 1>,...
